[Gambas-user] Re; Component writing ...

[Gareth Bult]

Mmm,

One of the strengths of Delphi was that third parties could make free or commercial components, distribute them as source code and end users could compile the package which would add it to the local component library. This led to LOTS of third party developers getting involved and took the strain of Borland having to produce all the code themselves.

I guess the first thing I should do is to make the GridEditor work inside the IDE, then send you some code.
Is there a howto or something documenting the "proper" way to add stuff to the IDE tree as a component?

Such a feature won't be done before the 2.0 release.

To debug a component, I usually run its project inside the IDE. I create a 
Main startup module or a FMain startup form for this purpose. Look in the 
gb.db.form component sources to see what I mean.

Alas all icons are located inside the IDE source code at the moment.

Just debug your component as explained above.

Gambas components are like drivers for the Linux kernel. I want them to be in 
the main source repository. Components outside of the main repository are a 
nightmare to manage, as modifying the interpreter API will break them without 
notice.

If you have made a useful component, just send it me for integration. But I 
will check first that the component is really useful, that it does not 
duplicate an already existing component behaviour, and that its interface is 
not too weird. :-)
